A Home Visiting Program for Pregnant Youth to Promote Early Brain Development II

April 22, 2020 updated by: Guilherme Vanoni Polanczyk, MD PhD, University of Sao Paulo

The Effects Over Early Brain Development of a Nurse Home Visitation Program for Pregnant Youth and Their Families Living in a Poor Urban Area in São Paulo, Brazil II

Home visiting programs for pregnant women aiming to improve mother-infant relationship has received worldwide attention in the past 30 years. These programs are considered an important strategy to improve women's health during pregnancy, aside from improving child's birthing conditions and allowing parents access to tools which will nurture and properly stimulate their baby, thus promoting emotional and cognitive development. Objectives: The "Nurse home visitation program for pregnant youth" aims to promote infant´s healthy development, from pregnancy to the first months of life, in a high-risk population. Methods: Eighty young pregnant women aged between 14 and 21 years were randomly allocated to the intervention or to usual prenatal care program. The "Nurse home visitation program for pregnant youth" was developed based on Albert Bandura's theory of self-efficacy, on Urie Bronfenbrenner´s bioecological model, which recognizes the importance of individual and family inclusion in various contexts of social life, on John Bowlby and Mary Ainsworth evolutionary theories of attachment, which involves the care practitioner addressing issues such as environmental health, life course and parenting, bond between mother and infant, and infant´s social and cognitive development. Neuropsychomotor development will be assessed at 3, 6, 12 and 24 months using the Bayley Scale of Infant Development. Brain development will be assessed via electroencephalography at 6, 12 and 24 months.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
167

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 20 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Nurse home visits
Nurse home visits biweekly.
Behavioral: Home visiting Program for Young Pregnant Women
The visitation program was elaborated based in the following theoretical principles: a) Albert Bandura's self-efficacy theory; b) Urie Brofenbrenner's bioecological theory, which recognizes the importance of the insertion of individuals in families in varied contexts of life in society; c) John Bowlby and Mary Ainsworth's attachment theory. The basic premises of the intervention are health care, environmental health, life course development, development of parenting ability, relationship with friends and family, and social service support.
NO_INTERVENTION: Usual care
Usual care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
